【mybrother后面的be动词接什么形式】在英语语法中,"be"动词的使用需要根据主语的人称和数进行变化。当主语是“my brother”时,它是一个第三人称单数的名词短语,因此“be”动词应选择“is”。
下面是对“my brother”后面接“be”动词的形式进行总结,并以表格形式展示。
一、
“my brother”是一个表示第三人称单数的主语,通常用于描述某个人的哥哥。在英语中,“be”动词有四种形式:am, is, are, was, were。其中:
- am 用于第一人称单数(I);
- is 用于第三人称单数(he, she, it);
- are 用于第二人称单数或复数(you, we, they);
- was/were 是过去时态中的“be”动词形式。
因此,在一般现在时中,“my brother”作为第三人称单数,其后的“be”动词应使用 is。
例如:
- My brother is a student.
- My brother is tall.
如果句子是过去时,则使用 was:
- My brother was a student last year.
二、表格总结
| 主语 | be动词形式(一般现在时) | be动词形式(一般过去时) | 例句 |
| I | am | was | I am tired. |
| You | are | were | You are welcome. |
| He/She/It | is | was | He is a teacher. |
| We | are | were | We are going to the park. |
| They | are | were | They are students. |
| My brother | is | was | My brother is a doctor. |
通过以上分析可以看出,“my brother”作为第三人称单数,后面接“be”动词时应使用 is,而如果是过去时态,则用 was。这种规则在英语中具有普遍性,适用于类似的第三人称单数主语。
